This should go to the ELisp manual, not the Emacs User manual.

GNU coding standards frown on using "path" for anything that isn't a
PATH-style list of directories.  We use "file name" instead, but in
this case you don't need even that: just say "the given @var{file}".

emacs.c is a file, so it should have the @file markup, not @code.

   ^^^^^^^^^^^^
You want @samp{Git} here, without the quotes.  The quotes might
mislead someone into thinking the result is a string.

Last, but not least: documentation changes need ChangeLog-style commit
log messages as well (just use "C-x 4 a" to get a preformatted
skeleton from which you could start).
